RAILWAY SIDE-FRAME AND JOURNAL-BOX CONNECTION.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed September 3, 1920. Serial No. 407,831.

To all wiwm it may concern:

Be it known that I HARRY E. Donne, a citizen of the United tates,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Railway Side-Frame and Journal-Box Connections,of which the following is a specification.

This invention relates to a railway side frame and journal boxconnection.

The object of the invention is to provide a simple, reliable andfficient means for permitting the journal box to move guidedly in avertical direction in the side frame pedestal jaws to accommodate thereception of shims .of different sizes between the side frame and box.

Another object is to provide a simple, relatively movable connectionbetween the truck side frame and journal box adapted to meet the variousrequirements of service conditions.

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet of drawings, in which- Figure 1 is afragmentary longitudinal sectional view of a truck side frame andjournal box connected thereto in accordance with my invention;

Fig. 2 is a sectional view of the same taken in the plane of line 2-42of Fig. 1; and,

Figs. 3 and 4 are side and end elevations, respectively, of a shim whichis insertible between the journal box and side frame.

It is common practice in compensating for wheel wear to build the sideframe with a tie bar extending underneath the journal box and spacedtherefrom by interposed removable shims. In the course of time the truckwheels wear to such an extent as to make truing necessary, which truingreduces the diameter of the wheels and would result in a lowering of thecar coupler if provision were not made to compensate for such reduction.Usually one of the shims below the journal box is removed and theninterposed between the top of the journal box and the truck pedestal.Then after another period of use the wheels are again trued and anothershim is transferred from below the journal box to the top thereof. Thisarrangement requires that every truck be provided with ieust eight shimsat the time the truck is built and applied to the car, which shimsincrease the weight of the truck, the cost thereof, and the weight to bepulled by the locomotive. I overcome these objectionable features bymeans of the arrangement disclosed on the accompanying sheet ofdrawings, wherein it will be noted that I have provided an integrallyformed truck side frame 10 having depending pedestal jaws 11, eachhaving spaced flanges 12 pro viding vertical guiding pockets 13 for thereception of laterally extending ears 14 of a journal box 15, said earshaving elongated slots or openings 16 which register with openings 17 inthe pedestal jaw flanges 1.2 and which registering openings 17 andelonga slots 16 receive fastening means which may take the form of bolts18. From this arrangement it is apparent that both sides of the journalbox may move guidedly in a vertical plane within the pedestal jaws 1].for varying the distance between the top of the jornal box and the innerupper surface 19 between the pedestal a ws 11, whereby shims 20 ofdifferent thicknesses ma be iiiserted the1'ebetween in accordance withwear and truing of the truck wheels. in this instance the shims 20 arearcuate in shape and have upstanding flanges 21 which embrace oppo sitesides of the side frame at the journal box receiving portion 19. Bymeans of this arrangement a connection is formed between the truck "dcframe and journai box adapted to meet the various requirements forsuccessful commercial use.

I claim:

1. In combination, in a railway car truck, a side frame having dependingpedestal jaws each having an opening, a journal box having laterallyextending ears with elongated slots therein to register with said otheropenings whereby both sides of the journal box may move guidedly in avertical direction to accommodate the reception of a shim between theframe and the box, and securing means extending through said registeringopenings and slots and which when in position will permit relativevertical movement between the box and jaws.

2. In combination, in a railway car truck, aside frame having dependingpedestal jaws each having spaced flanges for forming pockcts and saidflanges having registering openings, a journal box having laterallyextend ing ea rs provided with elongated openings in register with saidother openings whereby both sides of the journaL box may move guidedlyin said box between said flanges in a verti'c'a1 direction toaccommodate thereceptioil of-"a shim between the frame and theboxya'ndsecuring means extending through said registering openings insaid flanges and ears and which when in position will permit relativevertical movement between the box 10 and jaws. r

Signed at St. Louis Missouri, this 30th day of August, 1920. I
